I'm a software engineer with a creative mind, and I’m passionate about learning new things and solving complex problems. I work best in a horizontal and collaborative team that autonomously interacts with all aspects of the product we are developing.

I'm currently looking for a dynamic environment where I'll be able to broaden my knowledge and do things with love.

I speak native Portuguese πŸ‡§πŸ‡·, fluent English πŸ‡ΊπŸ‡Έ and advanced Spanish πŸ‡ͺπŸ‡Έ.
